在capistrano部署后，Rails 4未检测到应用程序

我目前正在尝试使用Capistrano 3部署Rails 4应用程序。一切顺利，但我遇到了一个问题，是的！我无法在我的应用程序中运行任何rails命令。在capistrano部署后，Rails 4未检测到应用程序

这里是我的相关Capistrano的插件：

gem 'capistrano-rails' 
gem 'capistrano-unicorn-nginx' 
gem 'capistrano-rbenv' 
gem 'capistrano-secrets-yml' 
gem 'capistrano-rails-console'

所以，当我运行一个cap production rails:console它给我这样的输出：

[b2458a1e] Running /usr/bin/env [ -d ~/.rbenv/versions/2.1.1 ] as [email protected] 
DEBUG [b2458a1e] Command: [ -d ~/.rbenv/versions/2.1.1 ]

    -T, [--skip-test-unit], [--no-skip-test-unit]   # Skip Test::Unit files 
     [--rc=RC]

任何想法？

更新13/03 - 增加deploy.rb

# config valid only for current version of Capistrano 
lock '3.3.5' 

set :application, 'my_app' 
set :repo_url, '[email protected]:foo/my_app.git' 

# Default branch is :master 
# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }.call 
set :branch, 'master' 

# Default deploy_to directory is /var/www/my_app_name 
set :deploy_to, '/var/www/my_app' 

# Default value for :linked_files is [] 
set :linked_files, fetch(:linked_files, []).push('config/database.yml') 

# Default value for linked_dirs is [] 
set :linked_dirs, fetch(:linked_dirs, []).push('bin', 'log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system') 

set :rbenv_ruby, '2.1.1'

'rails：console'任务来自哪里？我没有看到它列出的任何capistrano宝石提供的。 – 2015-03-13 19:30:20

你确认了什么Rails环境被调用？（正在看你的'INFO [2d552562]正在运行〜/ .rbenv/bin/rbenv exec bundle exec rails console production as user @ x.x.x.x' line）。你能够直接登录到服务器并使用'相同的bundle exec'命令来调用'rails c'吗？ – rdnewman 2015-03-13 19:31:30

@MattBrictson它来自这个插件（capistrano-rails-console）https://github.com/ydkn/capistrano-rails-console – Awea 2015-03-13 19:47:34

我认为问题是，你缺少你的Rails应用程序的部署副本的bin/rails。这是我会做的：

确保您的bin目录的内容被添加，提交并推送到您的git存储库。这将包括bin/rails和bin/rake。
删除bin来自Capistrano的:linked_dirs设置在您的deploy.rb中。
重新部署。
